Combined cataract extraction and Baerveldt glaucoma drainage implant: indications and outcomes.

Objective: To report the indications and outcomes of simultaneous cataract extraction (CE) and Baerveldt glaucoma drainage implant surgery.

Methods: Noncomparative, interventional, retrospective, consecutive case series. Methods: Thirty-three eyes of 33 patients. Methods: Combined phacoemulsification CE and Baerveldt glaucoma drainage implant (BGI) surgery at two tertiary care referral centers. Methods: Visual acuity, intraocular pressure (IOP), and complications.

Results: The study included 33 eyes of 33 patients followed for an average of 15.4 months (range, 3.0-46.9). The most common indication for combined CE and Baerveldt glaucoma drainage implant surgery was a history of prior failed trabeculectomy. Postoperative visual acuity at last follow-up was > or =20/40 in 12 of 33 patients (36%). IOP was reduced from a mean (+/- standard deviation) of 21 +/- 7.3 mmHg preoperatively to 13.1 +/- 3.5 mmHg at last follow-up visit ( P < 0.001). The number of antiglaucoma medications was reduced from a mean (+/- standard deviation) of 2.3 +/- 1.0 preoperatively to 0.7 +/- 1.1 at last follow-up (P < 0.001). Three eyes met our criteria for failure, and cumulative survival of the glaucoma surgery at 18 months was 89%. Intraoperative complications were all related to the cataract surgery, whereas early and late postoperative complications were related both to the CE and BGI surgery.

Conclusions: Combined CE and Baerveldt glaucoma drainage implant placement seems to be a safe and effective surgical option and may be preferred in certain clinical situations.
